Insulation in Oak Park, IL
In Oak Park, crawl space encapsulation and vapor barrier work is the highest-leverage insulation upgrade for pre-war homes, because balloon-framed Victorians and Prairie Style houses pull moisture up from dirt floors through continuous wall chases all year. The result is damp, drafty first floors and high heating bills from a house that literally breathes through its foundation. Fixing this starts with sealing the crawl space, then moving up through the walls and attic. That’s the order we work in, because it’s the order Oak Park’s housing stock demands.

Why Oak Park Homes Are Different
Oak Park’s residential streets are an architectural archive. Most homes between Ridgeland and Oak Park Avenue went up between the 1880s and 1930s: Victorians, Queen Annes, American Four-Squares, Craftsman bungalows, and the Prairie Style houses that made the village famous. They share a construction method that changes every insulation decision: balloon framing. Stud cavities run continuously from basement sill to attic with no floor-level fire blocking. That means blown-in insulation can settle or fall straight to the foundation if fire stops aren’t retrofitted first. We see this failure mode constantly, homeowners call us because a previous contractor’s work “disappeared.”
On top of that, the village’s Historic Preservation Commission restricts exterior insulation strategies on designated properties. In neighboring Berwyn or Forest Park, a crew might wrap a house in exterior rigid foam. In Oak Park, that’s often not permitted. Thermal upgrades have to happen from the inside, which demands more precision and more care around original plaster and trim. Our local crews do this work weekly.
Our Main Oak Park Services
Most Oak Park homeowners call us for two things: attic insulation (because hot air escapes through the tall, complex rooflines of Victorian and Prairie attics) and crawl space encapsulation (because balloon-frame foundations wick moisture into living spaces). Here’s what each involves in Oak Park.
Attic Insulation in Oak Park
Oak Park attics are rarely simple rectangles. The steep pitches, dormers, and knee walls common to the village’s older housing stock create dozens of thermal bypasses that a quick blow-and-go job will miss. We assess the full attic assembly first, then recommend the right approach: blown-in fiberglass or cellulose, spray foam for the roofline, or a combination. The goal is a sealed, well-insulated attic that holds heat in January and stays reasonable in July. Full details on our Attic Insulation in Oak Park page.

Crawl Space Encapsulation & Vapor Barrier in Oak Park
In Oak Park, a damp crawl space is rarely just a crawl space problem. In balloon-framed houses from the 1880s through the 1930s, unsealed dirt floors constantly release moisture that travels up through open wall chases and into the plaster above. The first floor smells musty, floors cup, and the furnace works harder because it’s heating wet air. Encapsulating the crawl space with a heavy-duty vapor barrier interrupts that cycle at the source. Our Crawl Space Encapsulation & Vapor Barrier work in Oak Park follows a specific sequence: clean and level the floor, seal foundation vents and rim joist gaps, lay a reinforced liner up the walls, and condition the space so it stays dry year-round.
Crawl Space Vapor Barrier
Signs you need it
Musty smell in the living room, cupped hardwood on the first floor, or visible condensation on ductwork or floor joists in the crawl space itself.
What it costs in Oak Park
Installing a crawl space vapor barrier in Oak Park typically runs $1,600 to $3,900 depending on square footage, access, and how much old debris has to come out first.
How we do it
We remove surface debris, level the soil where needed, and lay a 12-mil reinforced liner across the floor and up the foundation walls, taping all seams and sealing around piers.
Crawl Space Encapsulation
Signs you need it
Standing water after rain, a dirt floor that never fully dries, or an unmistakable damp-chill feel in the rooms above the crawl space.
What it costs in Oak Park
Full crawl space encapsulation in Oak Park, including sealing vents and conditioning the space, runs $4,000 to $12,000 based on square footage and whether a sump pump or dehumidifier is needed.
How we do it
We seal every opening: rim joists, foundation vents, and any penetrations. Then install the liner, then add drainage and a dehumidifier sized for the space, then verify the humidity level holds below 55%.
Crawl Space Insulation
Signs you need it
Cold floors in winter despite normal indoor temperature, frozen pipes along exterior walls, or heat loss at the rim joist band visible on thermal scan.
What it costs in Oak Park
Adding crawl space insulation to a Oak Park home typically falls between $1,200 and $3,400, though it’s usually combined with the vapor barrier for it to work correctly.
How we do it
Once the moisture is controlled, we install rigid foam on the walls or spray foam at the rim joist band, never fiberglass batts that would absorb moisture and fail.
What Crawl Space Encapsulation & Vapor Barrier Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Vapor barrier only | $1,600 - $3,900 |
| Full encapsulation | $4,000 - $12,000 |
| Crawl space insulation | $1,200 - $3,400 |
| Crawl space cleanout | $500 - $1,800 |
Every estimate includes the same written 90-Day Done Right Promise: if it’s not done right, we make it right.
Is encapsulation worth it for an older Oak Park home?
Yes, usually. In balloon-framed houses, an unsealed crawl space feeds moisture into the whole wall assembly. Encapsulation is the only reliable way to break that cycle and it often reduces heating costs on the first floor within the first season.
Can you fix a crawl space that floods after rain?
In many cases, yes. We install a sump pump and perimeter drain system, then seal the space. Call (855) 657-3403 and we’ll tell you if your crawl space can be waterproofed, and what it’ll take.
Spray Foam Insulation in Oak Park
Oak Park’s balloon-framed houses leak air in ways platform-framed homes simply don’t. Spray foam’s advantage here is that it expands into continuous wall chases, rim joists, and the odd attic geometries of Victorian and Prairie rooflines, creating an air seal and an insulation layer in one pass. We use open-cell foam for interior walls and attics where moisture permeability matters, and closed-cell foam where structural rigidity or a vapor barrier is required, like rim joists and basement sill plates. The result, a house that finally stops drafting. Our Spray Foam Insulation process is straightforward: test for existing moisture problems, prep the surfaces, spray to the specified depth, and verify every seam is filled.
Rim Joist Spray Foam
Signs you need it
Cold floors above the basement, drafts at the base of exterior walls, or visible gaps where the floor joists meet the foundation wall.
What it costs in Oak Park
Rim joist spray foam in Oak Park typically runs $60 to $120 per linear foot, and most full perimeter jobs finish in a single day.
How we do it
We air-seal the rim joist band with closed-cell foam, filling every joist bay to at least 2 inches, which cuts infiltration and sound transmission in one shot.
Garage Ceiling Spray Foam
Signs you need it
A bedroom above a garage that’s freezing in January, or a garage that radiates heat into the house in July.
What it costs in Oak Park
Garage ceiling spray foam in Oak Park generally falls between $1,800 and $3,200 depending on ceiling area and whether it’s an attached or detached garage.
How we do it
If the garage is attached to living space, we spray closed-cell foam directly to the ceiling cavity, creating an air barrier and thermal break where the house meets unconditioned space.
What Spray Foam Insulation Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Rim joist spray foam | $60 - $120 per linear foot |
| Garage ceiling spray foam | $1,800 - $3,200 |
| Open-cell attic spray foam | $1,800 - $6,000 |
| Closed-cell wall cavity foam | $2,500 - $8,000 |
Is spray foam safe in older Oak Park attics?
Yes, when installed by trained professionals with proper ventilation during application. Spray foam cures quickly and off-gasses minimally. We use Icynene and Demilec products with a long track record in residential retrofits, and we don’t cut corners on prep.
Can spray foam help with the historic commission’s exterior restrictions?
Exactly. Since exterior insulation is often not allowed on designated Oak Park properties, spray foam installed inside wall cavities or at the roofline delivers the same thermal benefits without altering the exterior. Call (855) 657-3403 to discuss your specific property.
Blown-In Insulation in Oak Park
Blown-in insulation works well in Oak Park attics and wall cavities, but the village’s balloon-frame construction demands one extra step that platform-frame suburbs skip: fire-stop blocking. Without retrofitted blocking at each floor level, loose-fill material settles or falls down the continuous stud chases, and the homeowner is left wondering why the insulation “disappeared.” We address that before we blow a single bag. For Oak Park’s tall Victorian attics, blown-in fiberglass or cellulose gives consistent coverage over the full floor, including the odd nooks and dormers that batts can’t reach. See our Blown-In Insulation page for material specifics.
Blown-In Cellulose
Signs you need it
An attic with less than 6 inches of existing insulation, or rooms that heat and cool unevenly despite an energy-efficient HVAC system.
What it costs in Oak Park
Blown-in cellulose in a Oak Park attic runs $1,200 to $2,800 for a standard 1,000-square-foot attic, including air sealing the top plates first.
How we do it
We dense-pack the material to the R-value specified for your home, usually R-49 in zone 5, and verify coverage with depth markers so every inch of attic floor gets the target amount.
Dense-Pack Wall Insulation
Signs you need it
Walls that feel hollow to the touch, rooms that stay cold near exterior walls in winter, or a balloon-frame home that’s never had cavity insulation.
What it costs in Oak Park
Dense-pack wall insulation in Oak Park, including drilling and patching access holes through original plaster or siding, typically runs $3,000 to $8,000 depending on house size and material.
How we do it
First we install fire-stop blocking at each floor line so the material can’t fall to the basement. Then we dense-pack the cavities under pressure, from the attic or through exterior access points, and patch every hole to match the existing surface.
What Blown-In Insulation Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Blown-in cellulose (attic) | $1,200 - $2,800 |
| Blown-in fiberglass (attic) | $1,300 - $3,000 |
| Dense-pack wall insulation | $3,000 - $8,000 |
| Blown-in top-up | $800 - $1,600 |
Does blown-in insulation work in balloon-framed walls?
Yes, but only with fire-stop blocking first. Otherwise the material settles or falls down the continuous stud chase to the foundation. This is the single biggest difference between insulating an Oak Park home and one in a platform-frame suburb.
How long does blown-in insulation last?
Cellulose typically lasts 20 to 30 years before settling becomes noticeable; fiberglass holds up somewhat longer. If your Oak Park attic has old, compressed material, we can top it up or remove and replace it in one visit.
Radiant Barrier Installation in Oak Park
Oak Park summers are hot and humid, and the tall attic spaces of Victorian and Prairie Style homes turn into ovens by late afternoon. That radiant heat pushes down into the second floor, making the air conditioner run far harder than it should. A radiant barrier installed to the underside of the roof deck reflects that heat back out before it ever enters the living space. In Oak Park, we pair the barrier with proper attic ventilation, because a radiant barrier without airflow just traps heat in the shingle deck. Our Radiant Barrier Installation work starts with checking that the attic has enough soffit and ridge ventilation to carry the reflected heat away.
Attic Radiant Barrier
Signs you need it
A second floor that’s consistently 5 to 10 degrees hotter than the first floor in summer, or an attic that’s unbearable by mid-afternoon.
What it costs in Oak Park
Attic radiant barrier installation in Oak Park typically runs $1,200 to $3,100 for a standard attic, including the barrier material and labor.
How we do it
We attach the foil-faced barrier to the underside of the roof rafters, leaving an air gap below the roof deck, then verify the attic’s exhaust ventilation can handle the reflected load.
Radiant Barrier & Ventilation
Signs you need it
An attic where the barrier would be installed but no soffit vents, ridge vents, or gable vents are present, or existing vents are blocked by old insulation.
What it costs in Oak Park
Combined radiant barrier and ventilation upgrades in Oak Park fall between $1,600 and $3,900, depending on how many new vents are needed and the roofline complexity.
How we do it
We first install or restore ventilation, then apply the radiant barrier. Without ventilation, the barrier can’t work, so we never do one without confirming the other.
What Radiant Barrier Installation Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Attic radiant barrier | $1,200 - $3,100 |
| Radiant barrier foil (material) | $350 - $750 |
| Roof deck application | $1,400 - $3,300 |
| Barrier plus ventilation | $1,600 - $3,900 |
Does a radiant barrier help in winter?
Somewhat. Its main job is reflecting summer heat. In January and February, the bigger wins in Oak Park come from air sealing and adding insulation to the attic floor. We’ll tell you honestly which one your house needs.
Can a radiant barrier be installed in an old Oak Park attic?
Usually yes, as long as the rafters are accessible and there’s enough headroom for our crew. The complex geometry of some Victorian rooflines takes longer, which can push cost toward the upper end of the range.
Insulation Removal & Replacement in Oak Park
In Oak Park’s older homes, we’re often called in because an attic has old fiberglass, vermiculite, or cellulose that’s been damaged by water, rodents, or decades of dust and is no longer performing. We remove it completely, sanitize the attic if needed, and install new material matched to the house’s construction era. This is especially common in the village’s pre-war Victorians and Four-Squares, where original insulation was often minimal and whatever was added later has been compromised by the same continuous wall chases that plague the rest of the house. Our Insulation Removal & Replacement approach is methodical: assess, remove, clean, air-seal, and re-insulate. Most Oak Park jobs finish in one visit.
Attic Insulation Removal
Signs you need it
Visible mold or damp spots in the attic, rodent droppings throughout the insulation, or material that’s compressed to half its original depth.
What it costs in Oak Park
Attic insulation removal in Oak Park typically costs $1,200 to $2,800 depending on attic size and how much material must be bagged and carried out.
How we do it
We use commercial vacuums and manual extraction, bagging everything on site, then we inspect the deck and joists for any damage that needs attention before new insulation goes in.
Vermiculite & Old Insulation Removal
Signs you need it
Any vermiculite present in an Oak Park attic, even if it’s covered by newer material, or old insulation that crumbles to dust when disturbed.
What it costs in Oak Park
Removing vermiculite or old, degraded insulation in Oak Park runs $2,000 to $5,500, including containment and disposal.
How we do it
We follow a strict containment protocol: sealed off attic access, negative-pressure vacuum where necessary, and full disposal through licensed channels. We never disturb vermiculite without proper controls in place.
What Insulation Removal & Replacement Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Attic insulation removal | $1,200 - $2,800 |
| Contaminated insulation removal | $1,800 - $4,200 |
| Vermiculite removal | $2,000 - $5,500 |
| Full replacement (including new insulation) | $2,500 - $7,000 |
Is vermiculite dangerous?
Some vermiculite contains asbestos. If your Oak Park attic has it, do not disturb it and do not attempt removal yourself. We can test it and, if needed, remove it under proper containment. Call (855) 657-3403 for guidance.
Can you remove old insulation in one day?
In most Oak Park attics, yes. Removal, cleanup, and new insulation typically happen in a single visit, though larger or heavily contaminated attics can take two days. We’ll tell you the timeline during the estimate.
Attic Air Sealing in Oak Park
In Oak Park’s Victorian and Prairie Style houses, the attic is the single biggest thermal hole. Warm air rises through every opening in the attic floor: top plates, can lights, plumbing penetrations, and especially the small gaps around original chimneys. In January and February, when Chicago’s wind chill settles over Oak Park, those bypasses create a stack effect that pulls cold air in at the foundation and pushes warm air out at the roofline. Sealing them first makes any insulation you add actually work. Our Attic Air Sealing service is the prerequisite to every attic insulation job we do in Oak Park, not an upsell.
Top Plate & Penetration Sealing
Signs you need it
Visible gaps where the attic floor meets exterior walls, dust marks around wires or pipes passing through the floor, or a noticeable draft in the rooms below.
What it costs in Oak Park
Top plate and penetration sealing in Oak Park attics typically runs $800 to $2,000 depending on how many penetrations need treatment.
How we do it
We seal every top plate gap and penetration with spray foam or caulk, then verify with a blower door test that the overall leakage rate has dropped.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights in the ceiling below the attic that feel warm, or rooms that never stay warm despite the furnace running constantly.
What it costs in Oak Park
Can light and duct boot sealing in Oak Park typically runs $400 to $1,200 per room, depending on how many fixtures and boots are exposed in the attic.
How we do it
We install sealed covers or boxes over each can light, seal around duct boots, and where fixtures are incompatible, we replace them with IC-rated air-tight housings.
What Attic Air Sealing Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Top plate and penetration sealing | $800 - $2,000 |
| Can light and duct boot sealing | $400 - $1,200 per room |
| Attic hatch sealing | $100 - $350 |
Does air sealing really cut heating bills in Oak Park?
Yes, usually by 10% to 20% when combined with adequate attic insulation. In balloon-framed homes, it’s the single most effective step because it stops the stack effect that pulls heated air out of the house.
Can you seal an old attic without damaging plaster?
Yes. Work is done from the attic side, not through the ceilings below. Original plaster and trim are left untouched. If access is tight, we work from drop cloths and planks placed over the joists.
Wall Insulation in Oak Park
Oak Park’s pre-1940 homes were built with little to no wall insulation, and the balloon-framed stud cavities make retrofitting that insulation an entirely different job than in newer construction. The village’s Historic Preservation Commission often prohibits exterior strategies, so we usually work from the inside: drilling through original plaster, dense-packing the cavities, and patching so the walls look untouched. But the hard truth is that in Oak Park, blown-in wall insulation can simply fall through to the foundation if fire stops aren’t retrofitted first. Our Wall Insulation crews install floor-level blocking before any cavity fill goes in, because without it the job fails and the homeowner pays twice.
Injection Foam Wall Insulation
Signs you need it
Cold exterior walls in winter, rooms that lose heat quickly after the furnace cycles off, or walls that feel hollow when tapped.
What it costs in Oak Park
Injection foam wall insulation in Oak Park typically runs $4,000 to $10,000 for an average-size home, including drilling, injecting, and patching every access hole.
How we do it
We install fire-stop blocking at each floor line, then inject slow-rise foam through small access holes drilled through plaster or siding, one cavity at a time, then patch and refinish each hole.
Interior Wall Soundproofing
Signs you need it
Conversations, footsteps, or plumbing noise carrying between bedrooms or between a living space and a home office in a converted Victorian.
What it costs in Oak Park
Interior wall soundproofing in Oak Park runs $1,500 to $4,500 per wall, depending on wall area and which materials you choose.
How we do it
We dense-pack the wall cavities with mineral wool or install a dedicated soundproofing assembly, often paired with air sealing to close the flanking paths that carry noise through old plaster.
What Wall Insulation Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Injection foam wall insulation | $4,000 - $10,000 |
| Drill and fill wall insulation | $3,000 - $8,000 |
| Interior wall soundproofing | $1,500 - $4,500 per wall |
Do I need fire-stop blocking before wall insulation?
In Oak Park’s balloon-framed homes, yes. Without blocking at each floor level, dense-packed material can settle or fall through the continuous stud chases. We install blocking as a standard part of every wall-cavity job in the village.
Will wall insulation damage my original plaster?
No. We drill small access holes and patch them to match the existing surface. Original trim and decorative plaster are left intact, and our crew is trained to work inside historic homes without disrupting the finishes.
Attic Cleaning & Rodent Proofing in Oak Park
Oak Park’s old attics, with their gable ends, soffit gaps, and original chimneys, are exactly the kind of spaces squirrels and roof rats like to call home. Rodents shred insulation, contaminate the attic with droppings, and gnaw on wiring, which is a real fire hazard in a 100-year-old house. We remove the contaminated material, sanitize and deodorize the space, then seal every entry point so the problem doesn’t come back. Our Attic Cleaning & Rodent Proofing work in Oak Park earns its keep because the housing stock is so attractive to pests.
Attic Cleanout
Signs you need it
Visible droppings, shredded insulation, nesting material, or an attic that smells like animal urine even after the weather changes.
What it costs in Oak Park
Attic cleanout in Oak Park typically runs $600 to $1,800 depending on attic size, depth of contamination, and whether the material is loose-fill or batts.
How we do it
We remove all contaminated insulation, vacuum the decking, and dispose of material through licensed channels, then assess what new insulation is needed.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in the walls or ceiling at dusk and dawn, droppings near the attic hatch, or chewed wood or wires visible in the attic.
What it costs in Oak Park
Rodent proofing and exclusion in Oak Park runs $800 to $2,500, depending on how many entry points are found and the roof geometry.
How we do it
We seal every entry point at gable vents, soffit intersections, and roof penetrations with galvanized mesh and sealant, then confirm with a follow-up inspection. We also address the chimney and kick-out flashing gaps typical in older Oak Park homes.
What Attic Cleaning & Rodent Proofing Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Attic cleanout | $600 - $1,800 |
| Sanitizing and decontamination | $500 - $1,400 |
| Rodent proofing and exclusion | $800 - $2,500 |
| Attic restoration (including new insulation) | $1,500 - $5,500 |
Can you clean an attic that’s had rodents for years?
Yes. We remove all contaminated material, sanitize the space, and replace the insulation. The key is sealing every entry point, or the rodents return. Call (855) 657-3403 and we’ll inspect your attic and give a straight answer.
Do you handle the trapping, too?
We focus on the attic: clean out, sanitizing, and exclusion. If live animals are present, we can refer you to a licensed wildlife removal specialist we trust, then we take over once the attic is clear.
Home Energy Audit in Oak Park
For Oak Park homeowners who want the full picture before spending on insulation, a home energy audit is the smartest first move. In balloon-framed houses, heat loss hides in places you can’t see: continuous stud chases, open rim joists, and attic bypasses behind original trim. Our audit finds them precisely. We bring a blower door and a thermal imaging camera, and we test the whole house, not just one room. The result is a room-by-room map of where your Oak Park home is losing energy, so every dollar you spend afterward goes exactly where it’s needed. Our Home Energy Audit is the diagnostic that makes every other service smarter.
Blower Door Test
Signs you need it
Higher-than-expected heating bills, drafts you can feel but can’t locate, or simply wanting to know how leaky your Oak Park home really is before any work begins.
What it costs in Oak Park
A blower door test in Oak Park typically runs $250 to $500 as a standalone test, or it’s included in a full home energy audit package.
How we do it
We mount the blower door in an exterior door frame, depressurize the house to 50 pascals, and measure exactly how much air leaks in, giving you a single number that benchmarks your home’s tightness.
Thermal Imaging Inspection
Signs you need it
Cold spots on walls or ceilings, rooms that never warm up, or moisture stains that suggest insulation has failed behind the plaster.
What it costs in Oak Park
Thermal imaging inspection in Oak Park runs $200 to $450 as a standalone scan, or it’s bundled into the full audit.
How we do it
With the blower door running, our technician scans every room with an infrared camera, capturing exactly where missing insulation, thermal bridges, and moisture problems are located.
What Home Energy Audit Costs in Oak Park
| Item | Typical range in Oak Park |
|---|---|
| Full home energy audit | $350 - $800 |
| Blower door test | $250 - $500 |
| Thermal imaging inspection | $200 - $450 |
| Duct leakage test | $200 - $400 |
Is a home energy audit worth it before insulating?
Yes, especially in Oak Park’s balloon-framed homes, where money spent in the wrong place is money wasted. The audit tells you exactly what to fix first. It pays for itself by preventing unnecessary or misdirected work.
Can you audit a house that still has original plaster walls?
Yes. Thermal imaging reads through plaster just fine. In fact, original plaster is often the best surface for revealing hidden cavities, thermal bridges, and missing insulation behind the wall.

FAQs About Insulation in Oak Park, IL
How quickly can you schedule insulation work in Oak Park?
We can usually get an inspector out to an Oak Park home within a few business days and start work once you approve the estimate. Most attic or wall insulation jobs finish in a single day, and crawl space or full-home projects typically take one or two days depending on access.
Do I need a permit for insulation work in Oak Park?
Standalone attic or wall insulation usually does not require a permit in Oak Park. On designated historic properties, the village’s Historic Preservation Commission does regulate exterior changes, so any insulation approach that would alter the outside of the home needs to go through that review first.
How does your written estimate process work?
We inspect the attic, walls, or crawl space in person, measure the area, and note anything that affects access or cost before writing up a fixed, itemized estimate. You approve the price in writing before the crew is scheduled, and it does not change once work begins.
Do you serve areas outside Oak Park?
We work throughout Oak Park and the surrounding communities, so homeowners in nearby neighborhoods and towns can use the same crews, the same pricing, and the same written estimate process without needing to find a separate local contractor.
What happens to the old insulation you remove?
We remove old insulation completely before installing anything new, bagging it for disposal and treating material that shows signs of rodent activity, mold, or heavy contamination with extra care. Attics with vermiculite or heavily soiled material get additional containment steps before removal begins.

What Oak Park Customers Say
"Injection foam in the walls of our 1950s house - no drywall demolition, just small holes patched and painted the same day. The street noise in the front bedroom is half what it was."
- Yasmin Farah"Upstairs was ten degrees hotter than downstairs every summer. They pulled the attic to bare joists, air-sealed every can light and top plate first, then blew it to R-49. First August in this house where the bedrooms and the living room read the same on the thermostat."
- Marcus Hale"Rodents had been in the attic for years before we bought the place. They vacuumed everything out, sanitized, sealed the entry points with mesh and foam, and only then put new insulation down. Photos of every stage before I paid."
- Darnell Whitfield
